7.3 LD (Logical Disk) Setting Procedure
When the disk drives are added to the disk array unit, the RAID level and logical disk (LD) must be
set appropriately.
Set the RAID level and LD (logical disk) by using the " NEC Storage Manager Software", or contact
your Service Engineer or NEC trained maintenance service representative who has expert knowledge
of the disk array unit for the setting of the RAID level and LD.
7.4 Spare Disk Setting Procedure
Spare disks can only be set in RAID levels 1, 5, 6, 10, or 50.
Set the spare disk by using the " NEC Storage Manager", or contact your Service Engineer or NEC
trained maintenance service representative who has expert knowledge of the disk array unit.
When you change a failing disk to a spare disk, confirm the capacity and rotational
speed of the spare disk are equal to that of the failing disk.
If your disk array unit contains disks of different capacities or different rotational
speeds, you should define a spare disk matching the capacity and rotational speed
of each disk in order to clarify disk management.
Up to 32 spare disks can be installed for the entire disk array unit.
